Description
この発明はコネクタに関する。 The present invention relates to a connector.
従来、図15、図16に示すように、ハウジング901に接点部材902、係合部材903及び動作部材904がそれぞれ装着されたコネクタが知られている(下記特許文献1参照)。 Conventionally, as shown in FIGS. 15 and 16, a connector is known in which a contact member 902, an engagement member 903, and an operation member 904 are mounted on a housing 901 (see Patent Document 1 below).
ハウジング901には、2個の係合部材903が装着されているとともに、10個の接点部材902が装着されている。10個の接点部材902は2個の係合部材903の間に配列されている。ハウジング901は、基板917が挿入される挿入用凹部906を有する。 Two engaging members 903 are mounted on the housing 901 and ten contact members 902 are mounted. The ten contact members 902 are arranged between the two engaging members 903. The housing 901 has an insertion recess 906 into which the substrate 917 is inserted.
動作部材904はほぼ長板状である。動作部材904の両端部には当接受部939がそれぞれ形成されている。当接受部939は傾斜部939Aを有する。動作部材904にはほぼ等間隔に溝部940が形成され、溝部940に軸部943が形成されることによって、動作部材904が回動可能に支持される。 The operation member 904 has a substantially plate shape. Abutment receiving portions 939 are formed at both ends of the operation member 904, respectively. The contact receiving part 939 has an inclined part 939A. The operating member 904 is formed with groove portions 940 at substantially equal intervals, and the shaft portion 943 is formed in the groove portion 940, whereby the operating member 904 is rotatably supported.
基板917をハウジング901の挿入用凹部906に挿入すると、まず基板917の先端が当接受部939の傾斜部939Aに当接する。 When the substrate 917 is inserted into the insertion recess 906 of the housing 901, the tip of the substrate 917 first comes into contact with the inclined portion 939A of the contact receiving portion 939.
基板917が挿入用凹部906に押し込まれると、基板917の先端によって当接受部939が押され、動作部材904は軸部943を中心として回転する。 When the substrate 917 is pushed into the insertion recess 906, the contact receiving portion 939 is pushed by the tip of the substrate 917, and the operation member 904 rotates around the shaft portion 943.
基板917が挿入用凹部906に押し込まれるにつれて動作部材904は起立位置に向かって回転する。 As the substrate 917 is pushed into the insertion recess 906, the operating member 904 rotates toward the standing position.
基板917が挿入用凹部906に更に押し込まれると、動作部材904は接点部材902の復帰力によって起立位置から水平位置に回転する。このとき、動作部材904の当接受部939が基板917の係止用切欠部918に係止され、ハウジング901からの基板917の脱落が防止される。 When the substrate 917 is further pushed into the insertion recess 906, the operating member 904 is rotated from the standing position to the horizontal position by the return force of the contact member 902. At this time, the contact receiving portion 939 of the operation member 904 is locked to the locking notch 918 of the substrate 917, and the substrate 917 is prevented from falling off from the housing 901.
上述のように、従来のコネクタでは、動作部材904の当接受部939が基板917の係止用切欠部918に係止されるので、ハウジング901から基板917が抜けにくい。 As described above, in the conventional connector, the contact receiving portion 939 of the operation member 904 is locked to the locking notch 918 of the substrate 917, so that the substrate 917 is not easily removed from the housing 901.
しかし、図17に示すように、基板917の係止用切欠部918に対する当接受部939の先端部の引っ掛り量は大きくない。 However, as shown in FIG. 17, the amount of engagement of the tip end portion of the contact receiving portion 939 with respect to the locking notch portion 918 of the substrate 917 is not large.
このため、なんらかの原因により基板917を引き抜く方向に大きな力が生じたとき、基板917がコネクタのハウジング901から容易に抜けるおそれがある。 For this reason, when a large force is generated in the direction of pulling out the board 917 for some reason, the board 917 may easily come out of the connector housing 901.

次に、この実施形態のコネクタ10の組立手順を説明する。 Next, the assembly procedure of the connector 10 of this embodiment will be described.
まず、複数の第1コンタクト50をそれぞれハウジング30の前方(図7Bの左側)から第1コンタクト収容室33に圧入する。 First, the plurality of first contacts 50 are press-fitted into the first contact accommodating chamber 33 from the front of the housing 30 (left side in FIG. 7B).
次に、ハウジング30の上方(図7Aの上側)から動作部材70を収容部32に挿入し、動作部材70の本体部71Aの両端部をそれぞれハウジング30の軸受部32Aに支持させる(図1参照)。 Next, the operating member 70 is inserted into the housing portion 32 from above the housing 30 (upper side in FIG. 7A), and both ends of the main body portion 71A of the operating member 70 are supported by the bearing portions 32A of the housing 30 (see FIG. 1). ).
最後に、複数の第2コンタクト60をそれぞれハウジング30の後方(図7Cの右側)から第2コンタクト収容室34に圧入する。 Finally, the plurality of second contacts 60 are respectively press-fitted into the second contact accommodating chamber 34 from the rear of the housing 30 (right side in FIG. 7C).
以上の手順を経てコネクタ10の組立が完了する。 The assembly of the connector 10 is completed through the above procedure.
次に、図7A〜図12Cを用いて、この実施形態のコネクタ10の動作を説明する。 Next, operation | movement of the connector 10 of this embodiment is demonstrated using FIG. 7A-FIG. 12C.
ハウジング30の挿入部31にフレキシブル配線基板80が挿入されていないとき、動作部材70の受け部72の上面72Cはハウジング30の上面部30Dとほぼ平行であり(図7A、図8A参照)、動作部材70の第1凹部71Bの内面71Dと第1コンタクト50の可動アーム部51の先端部51Aとは接触しておらず(図7B、図8B参照)、動作部材70の第2凹部71Cの内面71Eと第2コンタクト60の可動アーム部61の先端部61Aとは接触していない(図7C、図8C参照)。 When the flexible wiring board 80 is not inserted into the insertion portion 31 of the housing 30, the upper surface 72C of the receiving portion 72 of the operation member 70 is substantially parallel to the upper surface portion 30D of the housing 30 (see FIGS. 7A and 8A). The inner surface 71D of the first recess 71B of the member 70 is not in contact with the tip 51A of the movable arm 51 of the first contact 50 (see FIGS. 7B and 8B), and the inner surface of the second recess 71C of the operating member 70. 71E and the tip 61A of the movable arm 61 of the second contact 60 are not in contact (see FIGS. 7C and 8C).
フレキシブル配線基板80がハウジング30の挿入部31の挿入口31Aに挿入されると、動作部材70の受け部72がフレキシブル配線基板80に押されて回転し、受け部72がハウジング30の挿入部31から離れる方向へ移動する(図9A、図10A参照)。受け部72の回転につれて操作部71が回転(図10Bにおいて反時計回りの回転)すると、第1コンタクト50の可動アーム部51の先端部51Aが第1凹部71Bの内面71Dに押されて、挿入部31から離れる方向へ移動する(図9B、図10B参照)。同様に、第2コンタクト60の可動アーム部61の先端部61Aが第2凹部71Cの内面71Eに押されて、挿入部31から離れる方向へ移動する(図9C、図10C参照)。その結果、第1コンタクト50の第1接点部52と第2接点部57との間隔が広がる(図9B、図10B参照)とともに、第2コンタクト60の第1接点部62と第2接点部67との間の間隔が広がる(図9C、図10C参照)。したがって、フレキシブル配線基板80はハウジング30の挿入部31に小さな力で、あるいは無挿入力で挿入することができる。 When the flexible wiring substrate 80 is inserted into the insertion port 31 </ b> A of the insertion portion 31 of the housing 30, the receiving portion 72 of the operating member 70 is pushed by the flexible wiring substrate 80 and rotates, and the receiving portion 72 is inserted into the insertion portion 31 of the housing 30. (See FIGS. 9A and 10A). When the operation unit 71 rotates as the receiving unit 72 rotates (counterclockwise rotation in FIG. 10B), the distal end portion 51A of the movable arm portion 51 of the first contact 50 is pushed by the inner surface 71D of the first recess 71B and inserted. It moves in a direction away from the part 31 (see FIGS. 9B and 10B). Similarly, the tip 61A of the movable arm 61 of the second contact 60 is pushed by the inner surface 71E of the second recess 71C and moves away from the insertion portion 31 (see FIGS. 9C and 10C). As a result, the distance between the first contact portion 52 and the second contact portion 57 of the first contact 50 increases (see FIGS. 9B and 10B), and the first contact portion 62 and the second contact portion 67 of the second contact 60. (See FIGS. 9C and 10C). Therefore, the flexible wiring board 80 can be inserted into the insertion portion 31 of the housing 30 with a small force or with no insertion force.
フレキシブル配線基板80が更に挿入され、フレキシブル配線基板80の受容部85がハウジング30の上下方向UDでハウジング30の受容部35と対向すると、動作部材70の受け部72のロック部72Eがフレキシブル配線基板80の受容部85を通じてハウジング30の受容部35に入る(図11A、図12A参照)。このとき、操作部71は反対方向(図12Bにおいて時計回り)へ回転して第1コンタクト50の可動アーム部51の先端部51Aが第1凹部71Bの内面71Dに接触しなくなり、可動アーム部51の復帰力により挿入部31の方へ移動する(図11B、図12B参照)。同様に、第2コンタクト60の可動アーム部61の先端部61Aが第2凹部71Cの内面71Eに接触しなくなり、可動アーム部61の復帰力により挿入部31の方へ移動する(図11C、図12C参照)。その結果、第1コンタクト50の第1接点部52と第2接点部57との間隔が狭まる(図11B、図12B参照)とともに、第2コンタクト60の第1接点部62と第2接点部67との間隔が狭まり(図11C、図12C参照)、第1コンタクト50の第1接点部52がフレキシブル配線基板80の端子部82Aに接触し、第2コンタクト60の第1接点部62がフレキシブル配線基板80の端子部82A´に接触する。このようにしてフレキシブル配線基板80とプリント基板とが電気的に接続される。 When the flexible wiring board 80 is further inserted and the receiving portion 85 of the flexible wiring board 80 faces the receiving portion 35 of the housing 30 in the up and down direction UD of the housing 30, the lock portion 72E of the receiving portion 72 of the operation member 70 becomes the flexible wiring board. It enters the receiving portion 35 of the housing 30 through the 80 receiving portions 85 (see FIGS. 11A and 12A). At this time, the operation portion 71 rotates in the opposite direction (clockwise in FIG. 12B), and the distal end portion 51A of the movable arm portion 51 of the first contact 50 does not contact the inner surface 71D of the first recess portion 71B. Is moved toward the insertion portion 31 by the return force (see FIGS. 11B and 12B). Similarly, the distal end portion 61A of the movable arm portion 61 of the second contact 60 does not come into contact with the inner surface 71E of the second recess 71C, and moves toward the insertion portion 31 by the restoring force of the movable arm portion 61 (FIG. 11C, FIG. 12C). As a result, the distance between the first contact portion 52 and the second contact portion 57 of the first contact 50 is narrowed (see FIGS. 11B and 12B), and the first contact portion 62 and the second contact portion 67 of the second contact 60 are formed. (See FIGS. 11C and 12C), the first contact portion 52 of the first contact 50 contacts the terminal portion 82A of the flexible wiring board 80, and the first contact portion 62 of the second contact 60 is flexible wiring. It contacts the terminal portion 82A ′ of the substrate 80. In this way, the flexible wiring board 80 and the printed board are electrically connected.
フレキシブル配線基板80がコネクタ10に接続された状態(図12Aに示す状態)から、フレキシブル配線基板80をコネクタ10から引き抜こうとすると、フレキシブル配線基板80の受容部85の内面が動作部材70の受け部72の後面72Bに突き当たり、フレキシブル配線基板80が動作部材70の受け部72の後面72Bを挿入方向DIと反対の方向へ押すが、受け部72のロック部72Eがハウジング30の受容部35に深く入り込んでいるので、受け部72のロック部72Eの前面72Aがハウジング30の受容部35の内面に突き当たる。したがって、受け部72はほとんど回転しないため、フレキシブル配線基板80の挿入方向DIと反対の方向への移動は確実に阻止される。 When the flexible wiring board 80 is pulled out of the connector 10 from the state where the flexible wiring board 80 is connected to the connector 10 (the state shown in FIG. 12A), the inner surface of the receiving portion 85 of the flexible wiring board 80 is the receiving portion of the operating member 70. 72, the flexible wiring board 80 pushes the rear surface 72B of the receiving portion 72 of the operation member 70 in the direction opposite to the insertion direction DI, but the locking portion 72E of the receiving portion 72 is deeply inserted into the receiving portion 35 of the housing 30. Since it enters, the front surface 72 </ b> A of the lock portion 72 </ b> E of the receiving portion 72 hits the inner surface of the receiving portion 35 of the housing 30. Accordingly, since the receiving portion 72 hardly rotates, the movement of the flexible wiring board 80 in the direction opposite to the insertion direction DI is reliably prevented.
この実施形態によれば、何らかの原因によりフレキシブル配線基板80をコネクタ10から引き抜こうとする大きな力が生じたとしても、フレキシブル配線基板80はコネクタ10から容易に抜けない。 According to this embodiment, even if a large force for pulling out the flexible wiring board 80 from the connector 10 is generated for some reason, the flexible wiring board 80 does not easily come out of the connector 10.
また、動作部材70の受け部72を操作部71よりも後ろ(挿入部31の奥側)に配置し、フレキシブル配線基板80がハウジング30の挿入部31にある程度挿入された時点で、フレキシブル配線基板80が受け部72に接触する構造を採用したので、フレキシブル配線基板80を円滑に挿入部31に挿入することができ、フレキシブル配線基板80のハウジング30への挿入性が良い。 Further, when the receiving portion 72 of the operation member 70 is disposed behind the operation portion 71 (the back side of the insertion portion 31) and the flexible wiring substrate 80 is inserted into the insertion portion 31 of the housing 30 to some extent, the flexible wiring substrate. Since the structure in which 80 is in contact with the receiving portion 72 is adopted, the flexible wiring board 80 can be smoothly inserted into the insertion portion 31, and the insertion property of the flexible wiring board 80 into the housing 30 is good.
更に、第1コンタクト50の第1接点部52と第2コンタクト60の第1接点部62との位置が挿入方向DIでずれているので、第1コンタクト50と第2コンタクト60との配列ピッチを小さくでき、その分コネクタ10の長手方向LHにおける寸法を小さくできる。 Furthermore, since the positions of the first contact portion 52 of the first contact 50 and the first contact portion 62 of the second contact 60 are shifted in the insertion direction DI, the arrangement pitch between the first contact 50 and the second contact 60 is increased. Accordingly, the size of the connector 10 in the longitudinal direction LH can be reduced accordingly.
また、可動アーム部51,61にそれぞれ第1接点部52,62、第2接点部57,67を設けたので、フレキシブル配線基板80を挿入部31に挿入するとき、フレキシブル配線基板80の端子部82A,82A´がある面を上下どちらにしたとしても、フレキシブル配線基板80とプリント基板とは電気的に接続される。 In addition, since the first contact portions 52 and 62 and the second contact portions 57 and 67 are provided on the movable arm portions 51 and 61, respectively, when the flexible wiring board 80 is inserted into the insertion portion 31, the terminal portion of the flexible wiring board 80 is provided. The flexible wiring board 80 and the printed circuit board are electrically connected regardless of whether the surface with 82A, 82A 'is up or down.
フレキシブル配線基板80がロック部72Eによってロックされた状態からフレキシブル配線基板80をハウジング30から引き抜くには、治具等を用いて操作部71か受け部72を回転させて、ロック部72Eによるフレキシブル配線基板80のロック状態を解除し、フレキシブル配線基板80をハウジング30から引き抜くようにする。 In order to pull out the flexible wiring board 80 from the housing 30 from the state in which the flexible wiring board 80 is locked by the lock part 72E, the operation part 71 or the receiving part 72 is rotated using a jig or the like, and the flexible wiring by the lock part 72E is used. The locked state of the substrate 80 is released, and the flexible wiring substrate 80 is pulled out from the housing 30.
なお、コネクタ10には図15〜図17に示す従来のコネクタの係合部材903に相当するものがないので、部品点数が少なく、コネクタの構造が簡素である。 Since there is no connector 10 corresponding to the engagement member 903 of the conventional connector shown in FIGS. 15 to 17, the number of parts is small and the structure of the connector is simple.
また、従来のコネクタでは、係合部材903が基板917をハウジング901に挿入するときの抵抗となるが、この実施形態のコネクタ10には係合部材903に相当するものがないので、従来のコネクタよりも小さな力でフレキシブル配線基板80をハウジング30の挿入部31に挿入することができる。 In the conventional connector, the engaging member 903 provides resistance when the board 917 is inserted into the housing 901. However, since the connector 10 of this embodiment has no equivalent to the engaging member 903, the conventional connector The flexible wiring board 80 can be inserted into the insertion portion 31 of the housing 30 with a smaller force.
なお、この実施形態では、従来のコネクタの仕切り板907に相当するものがないので、第1コンタクト50をハウジング30の前方から圧入することができるとともに、第2コンタクト60をハウジング30の後方から圧入することができ、ハウジング30の前部に第1コンタクト50の接続部55を配置し、ハウジング30の後部に第2コンタクト60の接続部65を配置することができる。その結果、第1コンタクト50と第2コンタクト60との配列ピッチを小さくでき、その分コネクタ10の長手方向LHにおける寸法を小さくすることができる。 In this embodiment, since there is nothing equivalent to the conventional connector partition plate 907, the first contact 50 can be press-fitted from the front of the housing 30, and the second contact 60 can be press-fitted from the rear of the housing 30. The connection portion 55 of the first contact 50 can be disposed at the front portion of the housing 30, and the connection portion 65 of the second contact 60 can be disposed at the rear portion of the housing 30. As a result, the arrangement pitch between the first contacts 50 and the second contacts 60 can be reduced, and the size of the connector 10 in the longitudinal direction LH can be reduced accordingly.
次に、この発明の第2実施形態に係るコネクタを図13〜図14Cに基づいて説明する。 Next, a connector according to a second embodiment of the invention will be described with reference to FIGS.
第1実施形態と共通する部分については同一符号を付してその説明を省略する。以下、第1実施形態との主な相違部分についてだけ説明する。 Portions common to the first embodiment are denoted by the same reference numerals and description thereof is omitted. Only the main differences from the first embodiment will be described below.
コネクタ210の動作部材270は、受け部72に回転力を与えて受容部(ハウジング側受容部)235内のロック部72Eを挿入部31の外へ移動させるロック解除用操作部273を有する。更に、第1実施形態のハウジング30の受容部35が凹部であるのに対し、第2実施形態のハウジング230の受容部235は貫通孔である。この2つの点で、第2実施形態のコネクタ210と第1実施形態のコネクタ10とは異なる。その他の点では、第2実施形態のコネクタ210と第1実施形態のコネクタ10とは共通する。ロック解除用操作部273は操作部71及び受け部72に一体に設けられ、操作部71の本体部71Aと平行に延びている。 The operation member 270 of the connector 210 has a lock release operation portion 273 that applies a rotational force to the receiving portion 72 and moves the lock portion 72E in the receiving portion (housing side receiving portion) 235 to the outside of the insertion portion 31. Furthermore, the receiving portion 35 of the housing 30 of the first embodiment is a recess, whereas the receiving portion 235 of the housing 230 of the second embodiment is a through hole. The connector 210 of the second embodiment is different from the connector 10 of the first embodiment in these two points. In other respects, the connector 210 of the second embodiment and the connector 10 of the first embodiment are common. The unlocking operation portion 273 is provided integrally with the operation portion 71 and the receiving portion 72 and extends in parallel with the main body portion 71 </ b> A of the operation portion 71.
次に、コネクタ210の動作を説明する。 Next, the operation of the connector 210 will be described.
ハウジング230の挿入部31にフレキシブル配線基板80が挿入されていないとき、動作部材270のロック解除用操作部273は起立している(図14A参照)。 When the flexible wiring board 80 is not inserted into the insertion portion 31 of the housing 230, the unlocking operation portion 273 of the operation member 270 is erected (see FIG. 14A).

フレキシブル配線基板80がハウジング230の挿入部31の所定位置まで挿入されると、動作部材270の受け部72のロック部72Eがフレキシブル配線基板80の受容部85を通じてハウジング230の受容部235に入る(図14C参照)。その結果、フレキシブル配線基板80は受け部72のロック部72Eによってロックされる。 When the flexible wiring board 80 is inserted to a predetermined position of the insertion part 31 of the housing 230, the lock part 72E of the receiving part 72 of the operating member 270 enters the receiving part 235 of the housing 230 through the receiving part 85 of the flexible wiring board 80 ( (See FIG. 14C). As a result, the flexible wiring board 80 is locked by the lock portion 72E of the receiving portion 72.
フレキシブル配線基板80がロック部72Eによってロックされた状態からフレキシブル配線基板80をハウジング230から引き抜くには、図14Cに示す動作部材270の状態から、指でロック解除用操作部273を前方へ倒す(図14Bに示す動作部材270の状態を参照)。その結果、受け部72のロック部72Eがハウジング230の受容部235から抜け出し、ロック部72Eによるフレキシブル配線基板80のロック状態が解除され、フレキシブル配線基板80をハウジング230から引き抜くことができる。 In order to pull out the flexible wiring board 80 from the housing 230 in a state where the flexible wiring board 80 is locked by the lock part 72E, the unlocking operation part 273 is tilted forward with a finger from the state of the operation member 270 shown in FIG. 14C ( (See the state of the motion member 270 shown in FIG. 14B). As a result, the lock portion 72E of the receiving portion 72 comes out of the receiving portion 235 of the housing 230, the locked state of the flexible wiring board 80 by the lock portion 72E is released, and the flexible wiring board 80 can be pulled out from the housing 230.
第2実施形態によれば、第1実施形態と同様の作用効果を奏するとともに、動作部材270のロック解除用操作部273を指で操作することによって、ロック部72Eによるフレキシブル配線基板80のロック状態を解除することができるので、フレキシブル配線基板80をハウジング30から簡単に引き抜くことができる。 According to the second embodiment, the same effect as that of the first embodiment is achieved, and the lock state of the flexible wiring board 80 by the lock portion 72E is obtained by operating the unlocking operation portion 273 of the operation member 270 with a finger. Therefore, the flexible wiring board 80 can be easily pulled out from the housing 30.
